F A yr Fig. 6 is ai perspective view of amodified .form of brush head; g f. .Referring now more particularly tothe drawings,;the handle 5 ofthe brush is substantially fiat and curvedat its outer end in order to, conform to a persons hand, and is.formedjof any desired material, secured, to the outer end of the handlein a suitablel manner is a metal member, 6, provided just'beyond itspoint of attachment to the handle 5 with an elongated opening 7., theouter end 8 being of a tubular form eliptical in cross section, theextreme end 9 of the memher 6 being slightly flared outwardly.

Mounted within the tubular portion 8 is a clamping device 10, whichpreferably consists of a fiat metal member, provided with a circularheadl l, having a circularopening 12 a. By rotating the adjusting an 19the 551 5; .ing device 1 0v will vbe drawn rearwardly, the

As the brush headissecured tothe handle solely by frictional engagementwith the handie clamping member it will be noted that t my e r dilyturnedand edill e ed'tb ariousposition's as clearly shown-in Fig,

,withontopeliating the adjusting nut 1 9. 7 In Fig. -6 Ihave shown amodified form of brush headin'which the clamping member 24 isdispensedwith, the stud 25 being formed integral with the back of thebrush head 20 and preferably of the same material, this form beingconsideredimportant as maybe imanufactured much more economically thanthe form first described. 7 V V V It is well understoodthatapersonsteeth should be brushed in avertical direction towards andaway from the gums. By pro-I viding a comparatively small brush that maybe instantly adjusted at various angles with respect to the handle, aperson may readily brush the teeth in such manner, and further 5 theinterior surfaces may be readily reached for cleansing.

What I claim is: l. A toothbrush construction including a brush-headhaving an upstanding stud on the said brush-head, said handle having ahollow portion in the outer end thereof and a clamp,- ing mechanismslidably disposed in the hollow portion, said clamping mechanism beingadapted to engage said stud, and rotatable means disposed on the handleand in threaded association with said-clamping mechanism foroperatingthe same to frictionally clamp the mechanism to the stud.

2, A tooth brush construction including a brush-head, an upstanding studon the back of said brush-head, a handle provided with a slidable studgripping element, and means including a rotatable member, for detachablyconstricting the element about the stud on said brush-head tofrictionally clamp the handle to the stud.

3. A toothbrush construction including a brush-head, anupstanding studon the back ofsaid brush-head, and a detachable handle provided withspring clamping arms slidably associated therewith, and rotatable meansfor relatively displacing said arms to grip the stud and hold thebrush-head in adjusted relation with the handle.

4. A toothbrush comprising in combination, a back having an upstandingstud thereon, a handle having a hollow port-ion, means slidable,axially, substantially within the hollow portion of the handle, and athreaded element, rotatably engaging said means for detachably andfrictionally' associating the means and stud to clamp the handlethereto.

5. A toothbrush comprising a back having an upstanding stud formedthereon and a handle detachably attached thereto, said handie providedwith a tubular outer'end, the inner end of the tubular portion openinginto a nut receiving aperture, a stud clamping member having a studreceiving opening in its outer end and a rearwardly extending slotleading from said opening, whereby the size of the studopening may bedecreased in diameter, a threaded stud formed on the inner end ofsaidclamping member, and a nut disposed in the aperture of the clampingmember and engaging said threaded stud.

6. A toothbrush construction including a brush-head, an upstanding studon the back of said brush-head, a detachable handle provided with springclamping arms, and having a hollow portion to receive saidarms, the"arms being movable axially, in said hollow portion, for engaging thestud to hold the brush-head in adjusted angular relation to thebackthereof, and a handle pivotally engaging threaded means, rotatablerelative to and re.-

cessed within the handle, to operate 'the clamping means and connectsame with the han l 8. A toothbrush construction including a brush-head,an upstanding stud on the back of said brush-head, a handle having ahollow portion in the outer end thereof, a clamping mechanism disposedsubstantially within the hollow of said handle, said clamping mechanismbeing adapted to. engage said stud, and means, rotatable relative tosaid handle, associated with said clamping mechanism for operating thesame within said hollow portion to frictionally clamp. the mechanism tothe stud and to connect said mechanism with the handle.

9 A toothbrush comprising a handle having' a tubular portion, aresilient element, slidable relative to and extending into the tubularportion of the handle; rotatable means for moving said resilientelement, ax-. ially, relative to the handle; a brush-head, and means onsaid brush-head, frictionally and detachably embraced by said resilientcle ment whereby the brush-head and handle may be held in selectivepositions relative to each other.

10. A toothbrush comprising a brush-head; a handle having a hollowportion; a stud on said brush-head a variable tension clamp engaging thestud and extending into the'hollowportion; and means, associated withthe handle and in rotatable relation thereto, for operating the clamp,whereby the brush-head and handle may be detachably connected andwhereby selective and relative angular adjustment may be efiectedbetween the brushhead and handle,

11. A toothbrush construction including a brush-head having anupstanding stud thereon, a stud clamp, a detachable handle substantiallyenclosing said clamp, and a member rotatable relative to the handle andin threaded engagement with the clamp.

12-. In a tooth brush holder, a handle having a socket therein; aclamping mechanism slidably disposed in the socket and rotatable meansassociated with said clamping mechanism adapted to operate the same toengage a brush member. v

13. A tooth brush holder comprising a handle provided with a tubularouter end, the inner end of the tube opening into a nut re-CQlVlIlgflPltLllfG; a brush clamping member having a brushreceivingopeningin its outer end and a rearwardly extending slot leadingfrom said opening, whereby the opening may be decreased in diameter; athreaded stud formed on the inner end of the clamping member; and a nutdisposed in the aperture 5 and engaging said threaded stud.
